Bartók’s Viola Concerto remained unfinished at the time of his death in New York City in September of 1945, with its dedicatee William Primrose awaiting a call to meet the composer that would never come. The story of the completion of the concerto is well-known, with Bartók’s former composition student Tibor Serly hired to undertake what essentially became a reconstruction and re-composition (Serly had also orchestrated the Third Piano Concerto, which was a much more straightforward task).
